Rory Culkin Welcomes Baby Girl with Girlfriend Kate Arizmendi

Rory Culkin has become a father. The 36-year-old actor, known for his role in Scream 4, and his girlfriend Kate Arizmendi are now parents to a newborn daughter.

On Sunday, May 24, Arizmendi announced the arrival of their first child together via Instagram Story. The 38-year-old cinematographer shared the happy news along with a photo of their sleeping baby girl, named Havoc Moon.

"Her in the womb while I'm screaming System of a Down," Arizmendi wrote, before revealing the birth details: "Havoc Moon born 5/23 at 9:51. We're so in love [with] you."

Arizmendi has worked as a cinematographer on numerous productions, including the films and television series Swallow and Succession. The couple began dating in 2023, and Arizmendi revealed her pregnancy in January.

The birth of baby Havoc Moon follows a similar milestone in Culkin's family. In November 2025, his older brother Kieran Culkin and his wife Jazz Charton welcomed their third child together.
